The 2AS12 Card
Introduction
The 2AS12 is a broadcast quality dual channel composite decoder
with frame synchronizer. The 12-bit high performance digital
decoding stages provide superior quality 5 line comb filtering.
Because the 2AS12 (TWINS) has 2 fully independent channels, it
increases the Synapse decoding density by 100% and allows 36
individual composite decoders in 4 rack units. When no frame
synchronization is required the 2AS11 does the job.
Three Serial
